ABSTRACT OF THE DISCLOSURE A machine for lasting shoes having grippers for tensioning an upper over a last and wipers for wiping the lasting margin f the upper inwardly over and for pressing it against marginal portions of the bottom of the insole of the shoe, from the toe end back to the breast line, is also provided with a pair of nozzles movable lengthwise of the shoe for applying molten thermoplastic adhesive to the said marginal portions of the insole after the upper has been tensioned by the grippers and before the wipers are operated.

BACKGROUND OF THE INVENTION Field of the invention It is a common practice in the manufacture of shoes, to last shoes by tensioning the upper over a last and then wiping the lasting margin inwardly over the opposite marginal portions of the bottom of the insole of the shoe to cause the overlasted upper to be secured to said marginal portions of the insole by an adhesive, previously applied to the lasting margin of the upper, or to the upper and insole. The adhesives used in this procedure are generally of the solvent type which must be permitted to dry, after application, to a so-called tacky state.

A machine adapted for use in performing such a lasting operation is disclosed and claimed in U.S. Letters Patent No. 3,164,852, issued Jan. 12, 1965, in the names of Raymond M. Bowler and others. Such a machine, which is adapted to last only the toe end of a shoe, may be modified, in accordance with the disclosures of U.S. Letters Patent No. 3,226,745 issued Jan. 4, 1966, in the name of Gerard I. Marquis and No. 3,226,746, issued I an. 4, 1966, in the names of said Marquis and others, so as to last a shoe from toe end back to breast line. Moreover, in order to permit the use of a thermoplastic, or similar quick setting, adhesive for securing the overlasted margin of the upper to the insole at the toe end of the shoe, such a lasting machine may be further modied in accordance with a disclosure of an application for U.S. Letters Patent Ser. No. 460,095, filed June 1, 1965, in the name of Karl V. Becker, with means for extruding molten thermoplastic adhesive onto the marginal portion of the insole of a shoe in the machine, after the upper has been tensioned over the last and just before the lasting margin of the upper is wiped inwardly over and pressed against the bottom of the toe of the insole. With such a machine, while the application of a solvent type adhesive to the marginal portion of the toe end of the upper, or to upper and insole, and attendant drying period, are avoided, it is still necessary to perform these operations on the opposite marginal portions of the upper from about the tip line back to the breast line.

Summary of the invention It is an object of this invention to avoid the necessity for applying adhesive to the upper, or to upper and insole, prior to the lasting operation and also to make it possible to utilize a thermoplastic, or similar quick setting adhesive for securing the upper to marginal portions of the insole along the shoe bottom extending heelwardly from the toe end back toward or to the breast line. With this object in view, and in accordance with features of the invention, there is provided in a lasting machine of the type referred to above novel and improved means for applying a band of molten thermoplastic, or similar quick setting adhesive along the opposite marginal portions of the bottom of the insole of a shoe in the machine, after the upper has been tensioned over the last by the several grippers and just before the wipers are operated to wipe the lasting margin inwardly over and to press it against said opposite marginal portions of the insole, thus to secure the overlasted margin of the upper adhesively to the insole in lasted position.

More particularly, and in accordance with further features of the invention, the adhesive applying means comprises a pair of nozzle members mounted for movement first into engagement with the opposite marginal portions of the insole of a shoe in the machine in locations adjacent to the tip line and close to the toe nozzle member, then heelwardly along marginal portions of the insole extending toward or to locations adjacent to the breast line and finally heightwise away from the bottom of the shoe prior to the operation of the wipers. As the nozzles thus move along the marginal portions of the insole means are provided for yieldingly urging them toward each other to cause guide surfaces formed thereon to contact marginal edge portions of the insole, thus to position the nozzles relatively to the insole. Associated with the nozzles and connected thereto is mechanism for eX- truding molten thermoplastic adhesive through the nozzles in predetermined time relation to their respective movements along the marginal portions of the insole.

The above and other objects and features of the invention will appear in the following detailed description of the preferred embodiment which is illustrated in the accompanying drawings and will be pointed out in the claims.

Description of the preferred embodiment Referring to these drawings, the novel adhesive applying means of this invention is therein illustrated as applied to a machine adapted to last the entire forepart of a shoe from its toe end back to about the breast line thereof. Thus, the illustrated machine, which is generally similar to the machine disclosed in the Bowler et al. patent, referred to above, when modified in certain respects in accordance with the disclosures of the Marquis and Marquis et al. patents, also referred to above, has a shoe rest 20` (corresponding to the shoe rest 2 of the Bowler et al. patent), a toe gripper 24, a pair of side grippers 26, 26 and a pair of ball and shank grippers 28, 28 (corresponding, respectively, to the toe gripper 4, the side grippers 6, 6 and ball grippers 8, 8 of the Bowler et al. patent). This machine also has a pair of forepart wipers 34, 34 (corresponding to the forepart wipers 14, 14 of Bowler et al.), a pair of ball wipers 36, 36 (corresponding to the ball wipers 28, 28 of the Marquis patent) and a pair of shank wipers 38, 38 (corresponding to the shank wipers 32, 32 of the Marquis et al. patent). In addition, the illustrated machine has a heel clamp 40 (corresponding to the heel clamp 30 in each of the above-mentioned patents) a toe pad 42 (corresponding to the toe pad 40 of the Bowler et al. patent) a pair of side clamps 42, 42 (corresponding to the side clamps 25, 25 of the Marquis et al. patent) and a distributor 44 (corresponding to the distributor 10 of the Bowler et al. patent).

As is the case in the machine of the Bowler et al. patent, the toe gripper 24, side grippers 26, 26, ball and shank grippers 28, 28 and distributor 44 are also associated with, and actuated by fluid pressure operated members contained within, a main frame construction indicated generally by reference character 50, while the forepart wipers 34, 34, ball wipers 36, 36 and shank wipers 38, 38 are carried by an auxiliary frame member 52. This auxiliary frame member is mounted on the main frame construction for pivotal movement downwardly from the elevated position in which it is shown in FIG. l to a lower position in which the wipers are located at the proper level with respect to the bottom of a shoe supported on the shoe rest.

Briey described, with particular reference to the Bowler et al. patent, and insofar as is pertinent to a disclosure of the novel features of the present invention, the illustrated machine operates in the following manner: The operator places a shoe S, comprising an insole I and an upper U assembled on a last L on the shoe rest, see FIG. 2, and at the same time feeds the lasting margin of the upper into the open jaws of the several above-mentioned grippers. Now, in response to the depression of a foot treadle, not shown but corresponding to the foot treadle T, FIG. 1 of the Bowler et al. patent, the several grippers first close and then move downwardly away from the last to tension the upper over the last, at the toe end and along the opposite sides of the forepart and shank portions thereof. During this action of the grippers the auxiliary frame member 52, together with the wipers carried thereby, swings -downwardly to a so-called gauging position whereon the machine comes to a stop (see column 11, line 20, etc. of the Bowler et al. patent). The operator is now afforded an opportunity to correct the position of the upper relatively to the last, following which the machine cycle is continued in response to the pressing of a start button 60, FIG. 1 (corresponding to the button 481 of the Bowler et al. patent).

During the continued operating cycle of the machine, the auxiliary frame completes its downward movement whereupon the toe wipers, ball wipers and shank wipers are operated to wipe the lasting margin of the upper inwardly over and to press it firmly against the bottom of the insole of the shoe. As will be understood from the detailed description of the Bowler et al. patent, and see also Marquis and Marquis et al. patents, the several grippers are caused to release the upper in predetermined time relation to the action of the wipers, the toe rest is retracted and the toe pad is moved into engagement with the forepart of the shoe and caused to exert a downward pressure thereon to cause the wipers, which are now supporting the shoe, to apply a strong bedding down pressure on the overlasted margin of the upper. The machine then comes to a stop and dwells for a predetermined time interval, with the wipers exerting the bed down pressure, following which the toe pad is elevated and the heel clamp retracted to release the shoe and the other various operating elements resume their initial operating positions.

As suggested above, the herein illustrated machine is provided, in accordance with the disclosure of the Becker application, with means for applying molten thermoplastic adhesive to the toe end of the insole of a shoe in the machine. Referring to FIG, 2 of the drawings, this means comprises a nozzle member 70, of the shape shown in FIG. 4, mounted adjacent to the shoe rest 20. As is explained in detail in the Becker application, this nozzle, which corresponds to the nozzle member 60 of the Becker application, is mounted for vertical movement relatively to the shoe rest 20 and, during the operation of the lasting machine, is moved in time relation to the operation of the various lasting instrumentalities. Thus, the nozzle member is moved into the operative position in engagement with the toe end of the insole, in which it is shown in FIG. 2, after the upper has been tensioned by the grippers and before the wipers are operated.

This nozzle is connected to a source of molten thermoplastic adhesive under pressure by means of an electrically heated hose 72 and means, equivalent to those disclosed in the Becker application, are provided for controlling the ow of molten adhesive from its source through the hose to cause it to be extruded onto the toe end of the insole through apertures 74, 74 provided in the nozzle. Thereafter, this nozzle is moved downwardly and away from the insole to provide space for the advancing and closing of the wipers 34, 34 generally in the same manner as in the machine of the Becker application.

For the purposes of this invention, the herein illustrated machine is also provided with means for applying molten thermoplastic adhesive along the opposite marginal portions of the insole of the shoe being lasted extending heelwardly from about the tip line back to the breast line. This means comprises a pair of nozzle members 100, 100, FIG. 4, which are mirror images of each other. Each of these nozzle members is secured on the outer end of an elongated hollow housing 102 by means of a clamp screw 104, FIGS. 2 and 3, and is formed with a neck portion 106 having a rounded end 108 and an outwardly extending lip 110, FIG. 6. Secured inside of each housing 102 by means of the aforementioned screw 104 is a block 112 formed with a cylindrical bore 114 which is in alignment with an opening 116, in the end of the housing and one end of a passageway 118 formed in the neck portion 106 of a nozzle member and opening at the other end in the rounded end 108 thereof. Connected to each block 112 is a heated hose 120 which communicates with the bore 114 through an angled passageway 122 in the block 112 and with a source of molten adhesive under pressure, indicated generally by reference character 124, FIG. 1.

Rotatably mounted in each of the bores 114 is a cylindrical valve member 130, provided with an axially extending bore 132 and a radial port 134 in alignment with the passageway 122 of the block 112. As will be apparent, when these valve members are in angular positions corresponding to those shown in FIG. 3, molten adhesive under pressure will flow from the source 124 through the hoses 120, passageways 122, 122, valve members 130, 130, passageways 118, 118, and out through the rounded end portion of each of the two end nozzles 100, 100. Each valve member has formed integrally therewith an operating shaft which extends outwardly through and is journaled in the end of its associated housing opposite to the nozzle 100 thereof. Secured to each of these shafts, outside of the housing 102 is a lever arm 142. As will presently appear, means are provided, connected to these two arms, for rotating the shafts 140, 140, and valve members 130, 130 thus to control the ow of molten adhesive out through the nozzle members 100, 100. For heating each of the blocks 112 and nozzle members 100 associated therewith, an electrical heating unit 144 is provided.

Referring to FIGS. 3 and 5, each of the housings 102 is mounted on a supporting plate 150 by means of a rocker arm 152 having end portions which extend loosely through elongated apertures formed in ears 154, 154 on the housings and a pin 156 passing through a block 158 and a web portion 160 formed integrally with the plate 150. As shown in FIG. 3, each block 158 is pivotally mounted on a stud 162 carried by a housing 102. The supporting plate 150 is pivotally mounted between the upper ends of two arms 166, 166V which are secured to a rock shaft 168 journaled in forwardly extended portions 170, 170 of the main frame 50. Formed integrally with the plate 150 are two downwardly extending portions 172, 172 generally in alignment with the rocker arm 152, FIG. 5. Threaded into each of these downwardly extending portions of the plate 150 are adjustable abutment screws 174, 174, see also FIG. 4.

Journaled in the plate 150 are two bell crank levers 180, 180. One arm of each of these two levers is con nected, by means of a pin 182 and a slot 184 to one of the housings 102, while the other arm of each lever is connected to the rod 186 of a piston of a fluid pressure actuator indicated by the reference character 188. As will be apparent, by means of these actuators the two housings 102, 102 may either be separated to an extent determined by the settings of the adjusting screws 174, 174, or moved toward each other to cause the lip portions 110, 110 of the nozzle members 100, 100 to be held yieldingly in engagement with the marginal edge of the insole I of the shoe S when the nozzles are in their operating positions as shown in FIG. 6 of the drawings.

Referring to FIGS. 2, 3 and 4, the plate 158 is formed with an extension 190 and connected to this extension is the upper end of a link 192. At its lower end, this link is connected to an arm 194 formed integrally with a hollow shaft 196 which is rotatably mounted on a portion of the rock shaft 168. This hollow shaft also has another integrally formed arm 198 through the outer end of which there is threaded an adjusting screw 200 which is adapted to engage an abutment boss 202 on one of the frame members 170, thus to limit angular movement of the hollow shaft and pivotal movement of plate 150 in a counter-clockwise direction, as viewed in FIGS. 2 and 3. Connected to a third arm 204 formed integrally with the hollow shaft 196 is the rod 206 of the piston of a fiuid pressure actuator 210. Secured to the rock shaft 168 is an arm 220 which is connected to the rod 222 of the piston of a uid pressure actuator 224. The shaft 168 also carries an arm 230, FIG. l, which is adapted to actuate a first pilot valve 232 and a second pilot valve 234. The value 234 is mounted on the end of an arm 236 adapted to be held in a predetermined angular position on the frame member 170 by means of a clamp bushing, not shown, and a lock nut 240. Rotatably mounted on the clamp bushing is a second arm 242 carrying at its outer end the valve 232. A leaf spring 241 mounted on the arm 242 bears at one end against a lip 244, formed on the arm 236, and yieldingly swings the arm 242 in a clockwise direction, FIG. l, to the extent determined by the engagement of an adjustable stop screw 246 with the lip 244.

Mounted on the plate 150 is a fluid pressure actuator 250 having a piston with a piston rod 252. At its lower end, this piston rod carries a grooved disc 254 to which the arms 142, 142 associated with the valves 130, 130 are connected by means of wire links 256, 256, FIGS. 2 and 3. The arrangement is such that when the piston rod 252 is in its lowermost position, the valves 130, 130 will be opened, as shown in FIG. 3. On the other hand, when the rod 252 is elevated, these valves will be rotated to closed positions.

As is explained in the Bowler et al. patent. as well as in the Marquis et al. patents referred to above, the various operating elements of the lasting machine, including the grippers 24, 26, 26 4and 28, 28 are operated by means of a plurality of fluid pressure actuators under the control of pneumatic system disclosed in detail in the Bowler et al. patent. Also, after a shoe has been placed in the machine and the grippers operated to tension the upper over the last, the machine will come to a stop. Following this dwell period during which the position of the upper on the last may be adjusted, the machine is again started and the operating cycle is continued, during the initial stages of which the wipers 34, 34, 36, 36 and 38, 38 are operated. For the purposes of this invention, the uid pressure actuators 188, 188, 210, 224 and 250, together with suitable pneumatic control elements, including the pilot valves 232, 234, referred to above, are interposed in the fluid pressure system of the lasting machine so as to cause these actuators to operate in the following manner.

At the beginning of each operating cycle of the machine, the housing 102, 102 and nozzles 100, 100 are in the positions shown in FIG. 1 with the fluid pressure actuator 210 holding the stop screw 2001 against the abutment 202, fluid pressure actuator 224 holding the rock shaft 168 and arms 166, 166 in the positions shown, uid pressure actuators 188, 188 separating the nozzles 10), 100 to the extent determined by the adjusting screws 174, 174 and fluid pressure actuator 250' holding the valves 130, 130 in closed positions. Referring to FIG. 3, the nozzle is shown in this initial position and with the rounded end 108 thereof spaced slightly below the bottom surface of the insole I of the shoe which is resting on `the shoe rest 20. Also as shown in FIG. 1, the nozzles are located close to the heelward facing ends of the toe nozzle 70, see also FIG. 4. These nozzles remain in these positions while the upper is being tensioned over the last `by the grippers and until the machine is restarted, after the dwell and inspection period, to continue and to complete the operating cycle.

When the machine is restarted, the arms 1012, 102 are first swung upwardly by the actuator 210 thus to press the rounded ends 108, 188 of the nozzles 100, 100 yieldingly against the bottom of the insole I of the shoe S and the nozzles are moved toward each other by the fluid pressure actuators 188, 188, thus to bring the lip portions 110, of the nozzles into yielding engagement with the opposite marginal edges of the insole, FIG. 6. Next, the valves 130, are rotated to open position by the actuator 250, thus causing molten thermoplastic adhesive to be extruded from the ends of the passageways 118, 118 onto the marginal portion -of the insole and the arms 102, 102 and nozzles are moved lengthwise of the shoe, away from the nozzle member 70 and toward the heel end of the shoe by the actuator 224, which rotates the shaft 168 in a clockwise direction, FIG. 2 (counterclockwise in FIG. 1). At the same -time the valves 130, 130 are opened, the adhesive control means associated with the toe nozzle 70 is activated to cause a predetermined amount of adhesive to be extruded through the nozzle 70 onto the toe end of the insole. During such heelward movement of the arms and nozzles, the nozzles are held yieldingly against the bottom of the insole, by the actuator 210, and their lip portions are held yieldingly against the opposite marginal edges of the insole, by the actuators 188, 188. Thus, beads or bands of adhesive, B, B, FIG. 6, are spread along the opposite marginal portions of the insole from about the tip line back to the breast line thereof.

As the shaft 168 turns, the arm 230 thereof iirst engages and actuates the pilot valve 232, FIG. l, which causes the valves 130, 130 to be rotated by the actuator 250 to closed positions. Next, this arm engages and actuates the valve 234. The actuation of the valve 234, which occurs a predetermined time interval following the actuation of the valve 232, which interval can be varied by means of the adjustable screw 246, terminates the heelward movement of the arms 102, 102 and nozzles 100 by the actuator 224. Actuation of this valve also causes the actuator 210 to swing the arms 102, 102 in counterclockwise directions, FIG. 2, thus to move the nozzles downwardly and away from the bottom of the shoe, to an extent determined by the engagement of the stop screw 200 with the abutment 202. Actuation of the valve 234 also effects shifting of a valve forming a part of the pneumatic control system of the machine (corresponding to valve 582 of the Bowler et al. patent, see column 11, line 74) which commences the lasting cycle of the machine. As indicated above, the valves 130, 130 are closed to shut off the ow of adhesive through the nozzles 100, 100 before the heelward movements of the nozzles is terminated. Thus, during the final portions of such heelward movements the nozzles are wiped clean of adhesive.

By loosening the lock nut 240, FIG. 1, the arms 236 and 242 may be swung, as a unit, in a clockwise direction to angular positions in which the heelward movements of the two nozzles 100, 100 are terminated ahead of the breast line, for example at, or just beyond, the ball line of the shoe. Such limited heelward movements of the nozzles would be appropriate when the lasting machine, in accordance with a disclosure of the Marquis patent, is provided with ball wipers but does not have shank wipers, as disclosed in the Marquis et al. patent. Such a machine would be used where it was desired to last the shank portion of the shoe in another machine, for example a side lasting machine adapted to secure the lasting margin to the insole in lasted position by means of driven fastenings, i.e., staples or tacks.

During the continued operating cycle the several wipers are advanced and closed thus to wipe the lasting margin inwardly over and to press it against the opposite marginal portions of the insole I, from the toe end back to the breast line. As is explained in the above mentioned Becker application, the toe nozzle 70 is moved downwardly and away from the toe end of the insole, generally in the same manner as the insole holddowns (70) of the machine described in the Bowler et al. patent (see column l2, line l, etc.) either immediately before or just after the toe wipers 34, 34 commence their advancing movements. Following a predetermined time interval, during which the wipers are caused to apply the so-called bedding down pressure on the overlasted margin of the upper U, thus to secure it in lasted position to the insole by the previously applied adhesive, the shoe is rel-eased and the various operating elements of the lasting machine returned to their several original positions. Also, the actuator 224 is caused to rotate the shaft 168 in a counterclockwise direction, FIG. 2 (clockwise in FIG. 1), thus to return the arms 102, 102 and the nozzles 100, 100 to the starting positions in which they are shown in FIGS. 2 and 3.
